TRUCK-END CASTING.

SPECIFICATION forming part of Letters Patent No. 569,964, dated October20, 1896. Application filed July 15, 1896. Serial No. 599,234. (Nomodel.)

To all whom it may concern:

Be'it known that I, THOMAS EUBANK, a citizen of the United States,residing at the city of Little Rock, in the county of Pulaski and Stateof Arkansas, have invented a certain new and useful Improvement inTruck-End Castings, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, wherein- Figure 1 is a side elevational viewof my improved truck-end casting. Fig. 2 is an end view of the same.Fig. 3 is a detail view of the column-guides and spring-seat, only aportion of the latter being shown, however.

' Fig. 4 is a slightly-modified form inwhich the spring-seat isdispensed with, and a springplank or sand-board is shown in its place.

This invention relates to a new and useful improvement in end castingsfor trucks; and it consists in the construction, arrangement, andcombination of the several parts, all as will hereinafter be described,and afterward pointed out in the'claims.

In the drawings, A indicates the top archbar, B the bottom arch-bar, Othe tie-bar, and D the cross-tie bars, all of such parts being of anyordinary or approved construction.

E indicates the column-guides, which are 0 open at one side, the outer,the bottom, and top being closed by webs e and f, through which pass thecolumn bolts G. The top walls of these column-guides are connected,forming a top cross-bar F, in which the top 3 5 arch-bar Ais seated,said top cross-bar being formed with flanges or ribs at its sides toform said seat. Extending upwardly from the col umn-guides and at theends of this top cross bar are ears H, which project above the top 40arch-bar, said ears receiving rods or bolts I, which are also above thetop arch-bar. This I consider an important feature of my invention, asthese bolts or rods I take the place of the column-bolts should saidcolumn-bolts become broken or lose their nuts, as very frequentlyhappens in practice. Under such a condition the bolts or rods I wouldhold the column-guides up against the top arch-bar and retain the partsin position. The col- 5o umn-guides, being connected at their top by thecross-bar F, will not get out of alinement.

Thus it will be seen that even if the columnbolts were entirely removedthe truck would still be serviceable.

The column-guides, with their top crossbar, are substantially of aninverted U shape, and secured between the lower ends of the verticallegs, or at the lower ends of the column-guides, is a spring-seat J forsupporting the bolster-springs. This spring-seat is substantially T-shaped in cross-section, and is formed at its ends with ears j,extending on each side of the column-guides, to which they are secured,as will hereinafter appear. The base of the T is formed with sideflanges or ribs which form a seat between them for the lower arch-bar N.Suitable strengthening-websj' brace the top of the seat.

K indicates the truck-bolster, which is supported at its ends by springsL, said bolster having lips or ears k on each side of the column-guidesto guide the bolster in its vertical movement.

In assembling the parts the tie-rods O and D and the lower arch-bar areplaced in position. The spring-seat is arranged on the archbar, thesprings and bolster on top of that, and the column-guides now straddlethe bolster and fit between the ears j of the springseat. The toparch-bar is now arranged between the ears H, and the column-bolts passeddown through the respective openings made to receive them. The springs Lnot being under tension, the lower arch-bar will not be seated in thelower ends of the column-guides, and therefore the nuts on the lowerends of the column-bolts have to be turned up to bring the parts intoproper position. \Vhen the parts are thus brought together, boltopeningsin the ears j of the spring-seat and near the lower ends 01": thecolumn-guides register, so that a bolt or rod M may be passed through.This bolt or rod M, together with the column-bolts, holds the springs Lunder tension, and should the column-bolts break 5 or be removed afterthese bolts M were once in place said bolts M would serve to main tainthe proper relation between the column guides and spring-seats bypreventing inde= pendent vertical movement of either and by roe tyingthe lower ends of the column-guides against any spreading tendency.

In Fig. 4. I have shown a slight modification or an adaptation of thecolumn-guides having the top cross-bar to a spring-plank or sandboard.I11 this form the spring-seat is not used, but its place is taken by aspring-plank or sand-board N, which is secured to the lower ends of thecolumn-guides by suitable bolts passing through ears 0, projectinglaterally from the lower ends of said columnguides. In this modificationears P may also be provided at the lower ends of the columnguides,through which pass bolts Q under the lower arch-bar. This feature notonly gives strength and adds rigidity to the structure, but affords asupport for the lower arclnbar should the column-bolt become broken.

The operation of the parts is substantially the same and they areassembled in the same way, that is, the springs are placed under tensionby the column-bolts until the ears on the column-guides are in properposition rela tive to the spring-plank, when bolts are inserted tosecure the parts together. In this form, after the parts are allassembled if the column-bolts should become loose, broken, or evenremoved the truck would still be serv iceable.

There are many advantages incident to both of these constructions, chiefamong which are the rigidity it gives to the truck as an entirety, itssimplicity, compactness, cheapness, and safety. 7

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is- 9 1. The combination withthe arch-bars of a truck, of column-guides formed with ears or lugswhich extend above the top arch-bar, and bolts or rods in said lugs orears and on top of the top arch bar; substantially as described.

2. The combination with the arch-bars of a truck, of column-guidesformed with a c011- necting-bar at their upper ends in which the toparch-bar is seated, lugs or cars extending up from these column-guidesor cross-bars, above the top arch-bar, bolts or rods in said lugs, aspring-seat to which the lower ends of the column-guides are secured,and columnbolts; substantially as described.

3. The combination with the arch-bars of a truck, of column-guides whoseupper ends are connected, said connection forming a seat for the toparch-bar, lugs II extending up above the top arch-bar, bolts or rods Iin said lugs, spring-seats having ears extending on each side of thecolumn-guides, and bolts or rods which pass through said ears andcolumnguides; substantially as described.

4. The combination with the arch-bars of a truck, of column-guidesformed with ears or lugs which extend above and below said archbars,respectively, and bolts or rods in said lugs or ears for supporting theparts in the event of the column-bolts breaking or becoming loose;substantially as described.

In testimony whereof I hereunto afiix my signature, in presence of twowitnessses, this 15th day of June, 1890.
